摘要： A mobile crane includes an under carriage, a superstructure that is rotatably mounted on the superstructure, and a main boom, which is composed of a base body and several telescopic lengths up to a predetermined maximum number, which slide into one another and can be extended from the base body. The main boom is mounted on the superstructure so that it can rotate about a horizontal axis and its inclination can be adjusted by means of a hydraulic tilting cylinder that is hinged on the superstructure and the base body. A maximum permissible weight is predefined for the main boom, as a result of a restriction on the permissible axle load of the mobile crane during road haulage. The crane is also provided with a lifting capacity increasing device, which significantly increases the lifting capacity of the main boom when the telescopic lengths are extended, in relation to the state without the lifting capacity increasing device. The lifting capacity increasing device, as part of the standard basic equipment of the mobile crane, is connected in a fixed manner to the main boom, while maintaining the maximum number of telescopic lengths that are carried.
摘要翻译：移动式起重机包括下支架，可旋转地安装在上部结构上的上部结构，以及主起重臂，其由基体和几个伸缩长度达到预定最大数量组成，彼此滑动并可延伸从基体。主悬臂安装在上部结构上，使其能够围绕水平轴线旋转，并且其倾斜度可以通过铰接在上部结构和基体上的液压倾斜缸来调节。由于在公路运输期间对移动式起重机的允许轴负载的限制，主臂的最大允许重量是预先确定的。起重机还具有提升能力增加装置，当伸缩长度延长时，相对于没有提升能力增加装置的状态，这显着增加了主起重臂的提升能力。作为移动式起重机的标准基础设备的一部分的起重能力增加装置以固定的方式连接到主起重臂，同时保持承载的最大数量的伸缩长度。

摘要： A crane includes a telescopic jib having telescopic jib sections and a base jib. The telescopic sections are arranged so that they can be axially moved into and out of the base jib individually. Locking pins are used hold the telescopic sections in place once they are in the required position. A hydraulic piston-cylinder unit arranged in the telescopic jib can push or pull individual jib sections when the respective locking bolts are removed. The movable portion of the piston-cylinder unit has two securing and locking units located at opposing ends of the movable portion. To move the jib section, one of the securing and locking units is connected to the jib section to be moved and the movement of the movable portions pushed or pulls the telescopic section. Once the jib section is moved to a desired position, the locking pin is reinserted to hold the position of the jib section. Since there are two securing and locking units, the piston-cylinder unit is approximately half the length of the telescopic section.
摘要翻译：起重机包括具有伸缩臂架部分和底架的伸缩臂。伸缩部分被布置成使得它们可以单独地轴向地移入和移出基架。一旦使用锁定销就可以将伸缩部分固定在适当位置。布置在伸缩臂中的液压活塞 - 气缸单元可以在拆卸相应的锁定螺栓时推动或拉动单个悬臂部分。活塞 - 气缸单元的可移动部分具有位于可动部分的相对端的两个固定和锁定单元。为了移动起重臂部分，固定和锁定单元中的一个连接到起重臂部分以移动，并且可动部分的移动推动或拉动伸缩部分。一旦将起重臂部分移动到期望的位置，则锁定销被重新插入以保持起重臂部分的位置。由于存在两个固定和锁定单元，所以活塞 - 气缸单元大约是伸缩部分长度的一半。

摘要： A telescopic crane, includes a substructure, a superstructure rotatably mounted onto the substructure, a counterweight and a telescoping boom structure which includes a main boom slewable about a luffing plane. The main boom has a boom base and at least one telescope section received in the boom base and displaceable between retracted and extended positions. At least one guy support is mounted to the boom structure and connected to a guy rope which extends substantially longitudinally in the direction of the boom structure. The guy support is oriented with respect to the luffing plane at an inclination which is so selected that a lateral load acting on the boom structure is partially or entirely received by the guying.

摘要： A telescopic boom for crane, in particular mobile cranes, includes a base section and a plurality of boom sections received in the base section and telescopically extendible and retractable. The base section and the boom sections are each made of a profile comprised of an upper shell and a lower shell which are joined together at their confronting walls, with the upper shell having a nominal wall thickness which is equal or smaller than a nominal wall thickness of the lower shell. At least one portion of the upper and lower shells includes, as viewed in cross section, two outer thin metal sheets which are placed in spaced-apart relationship to define an intermediate space therebetween.

摘要： The present invention relates to a mobile crane boom having a self-sufficient energy supply arranged on it for supplying hydraulic energy to at least one hydraulic load arranged on the mobile crane boom. The supply of the hydraulic load arranged on the mobile crane boom is therefore not carried out by means of a hydraulic unit arranged on the revolving superstructure of the crane, which provides the hydraulic energy to each hydraulic load via hoses, but by means of a hydraulic unit which is arranged in the upper reaches of the mobile crane boom or in the area of the linkage of any second boom section. By arranging the hydraulic unit directly on the boom, the hoses normally required for supplying the hydraulic loads can be eliminated.

摘要： A telescopic boom section for a mobile crane including an upper inverted U-shaped longitudinal section and a lower convexo-concave longitudinal section. The upper section and the lower section are welded to each other along the seams formed by the longitudinal edges of the upper and the lower sections such that the concave surface of the lower section and the U-shaped wall of the upper section defines a cavity therewithin. The lower section includes a plurality of arcuate segments disposed sequentially across the concave surface and which are formed by a cold roll die.
